Hello programmers , as a beginner of pharo i have the following question. I suppose that you are lying under the tables for laughing flash !! hahaha To familiarize with the coding - saving - starting in general of smalltalk , may i ask you to make a short : step by step guide , to create a program that shows : " Hello World ". a pharo image self starting program " hello world" . ______________________________________________________________ 1. Package name : World 2. Class name : CreateWorld 3. Method of CreateWorld : Transcript show: 'Hello World' Now here are the steps to do point by point to SAVE the program as another image. The copy of the image should be starting direct in full screen and show : Hello World I think this "huge" task will motivate the creative developer ! Hans

Mouse wheel scrolling not working right on Windows
by Jan B. Oct. 28, 2014

Oct. 28, 2014

Hello I am reposting this from Moose mailing list, because it seems like problem in Pharo itself. In HandMorph>>#generateKeyboardEvent: is a condition based on charCode which tells whether incoming input event is of keyboard type or mousewheel type (code quoted below). On Linux, when I use mouse wheel, keyValue and charCode are both 30 or 31 respectively. But on Windows there is keyValue 30 or 31, but charCode 0. This condition is based on charCode being 30 or 31 so it absolutely never returns MouseWheelEvent. When I replace charCode with keyValue there, mouse wheel works fine (but I am not sure whether it might not break something else). Pharo core windows like System browser or Monticello seem to somehow get around it and work, but nothing else, like Roassal where I reported this bug before, so in whole Roassal mouse wheel does not work on Windows.

Pharo program "examples"
by Hans Schueren Oct. 28, 2014

Oct. 28, 2014

Thanks Jan , i know that the system itself is the program. But there must be "Image" programs out there to download. I only want to download a program ( Folder with image and exe [Pharo Container] ) Online. Just to see and start the program and see how it opens. ( like a normal program [ Pharo IDE is shadowed] ). Guess that i am a user. I have heared about Pharo and want to test a real program. Hans Hello again , are there any Pharo Program examples online ? I dont mean normal examples from coding. What i mean are end-user programs. Completely ready Online for downloading. Regards Hans

using pillar and/or pillarhub
by Peter UhnÃ¡k Oct. 28, 2014

Oct. 28, 2014

Hi, I wanted to experiment with Pillar however I'm not sure what to use to edit it. I was expecting some kind of editor with preview directly in Pharo but there is nothing. The next best thing I found was PillarHub based on Ace editor, however it depends on Mozilla Persona. Is such thing needed? If I'm running it locally why would I need to login somewhere? You don't log in to IDE when you want to program. Also such thing requires internet connection and is all extra nuisance when used on localhost. Is there a way to disable it? Do you use this setup, or are you all writing it in vim/emacs and only compile it once in a while? Thanks, Peter

Self-removing announcement subscription?
by Jan B. Oct. 27, 2014

Oct. 27, 2014

Hi all Today I come with a question regarding announcements. I would like to make announcement subscription which would remove itself after first use. Something like... anObject announcer subscribe: TRMouseDragEnd do: [ :event | self thisMethodWith: differentParameters. "anObject announcer removeSubscription: ...this one..." ]. All I was able to do is write there anObject announcer unsubscribe: self. which somehow works, but this instance could have multiple subscriptions and it would remove even those I don't want to remove, I need to remove only this specific one...

starting a program
by Hans Schueren Oct. 27, 2014

Oct. 27, 2014

Hello , thank you for the answers. I will "copy" the folder on USB stick in the first way. Other options as github and launcher later. It is a little bit strange to start a program. There is one package. Inside the package are two classes. To start ONE class i do with classname new classname. But what must i do to start the whole programm ? Normally , after i have started the complete program. I have to save the program as the "program image file". Then this image will display the program when it is opened from the pharo.exe file. The program should run immediatelly in full screen mode. This sounds strange questions.

starting a simple program - make EXE files for portable distrubution
by Hans Schueren Oct. 27, 2014

Oct. 27, 2014

Hello programmers , i am a beginner pharo. Now i have a complete , simple smalltalk program READY. The many functions of Pharo are not important for me at the time. What i want to do is the following : 1. starting the whole program in the Pharo environment ( not only a class or method ) 2. saving the image files only for the program in afolder. 3. storing the program image file on a USB stick. 4. starting and using the program on another PC. Theese questions seems to be simple for professionals. But let me explain the case. The program code in Pharo is included in all the classes and Methods. There is a package that contains many classes and different methods that represents the flow of the smalltalk program. During the writing i can check the methods and classes by sending a question to it and see the results. I have started a method by : method runmethod. or method new openInWorld. But what must i type to start the whole program ? If there are many classes ? How can i store the program in a optional image.file ? The program is indeed ready programmed. I have already realized that program code in Pharo is included in the image. Not as a file. Are there any online sites or instructions to do that ? Regards Hans
